G p Y is especially suitable for churches, assembly halls and large rooms. A stove of special design is placed in a chamber in the basement or cellar, and cold fresh air is passed through it, and led by means of flues to the various apartments for distribution by means of easily regulated inlet valves.
Of these features, the blast-pipe had been employed by Trevithick on his engine of 1804, and direct driving, without intermediate gearing, had been adopted in several previous engines; but the use of a number (25) of small tubes in place of one or two large flues was an innovation which in conjunction with the blast-pipe contributed greatly to the efficiency of the engine.
In flue curing, also known as the Virginian cure, fires are set outside the barn; and the heat led in iron pipes or flues, into the building are under the suspended tobacco, which is placed there quite fresh from the field.
In many mints the flues pass into condensing chambers where volatilized gold and silver are recovered.
[M] church has on its east side the "pisalis" or "calefactory" (H), the common sitting-room of the brethren, warmed by flues beneath the floor.
Beyond this we often find the calefactorium or day-room - an apartment warmed by flues beneath the pavement, where the brethren, half frozen during the night offices, betook themselves after the conclusion of lauds, to gain a little warmth, grease their sandals and get themselves ready for the work of the day.
Plant houses were formerly heated in a variety of ways - by fermenting organic matter, such as dung, by smoke flues, by steam and by hot water circulating in iron pipes.
It involves the keeping clean of flues, ashpits and especially the fires themselves.
Another plan in the greenhouse is to dash water on the pipes or flues, which causes steam to rise to the glass and freeze there, stopping up all the crevices.
Traces of thallium, which are present in some pyrites, may be detected in the flues of the furnaces where the metal is roasted.
II) differs from the Whitwell (I) in having not a series of flat smooth walls, but a great number of narrow vertical flues, E, for the alternate absorption and emission of the heat, with the consequence that, for given outside dimensions, it offers about one-half more heating surface than the true Whitwell stove; and (2) in that the gas and the blast pass only once up and once down through it, instead of twice up and twice down as in the modern true Whitwell stoves.
- Plan through Regenerators, Flues and Reversing Valves..
This is dug out, and after being dried on floors heated by flues is ready for burning.
The farther ends of the flues of several such kilns are connected with a chimney shaft.
In consequence the fire-gases, when arriving there by the chimney shaft (a), have already a good upward draught, and when circulatung round the muffle are at a lower pressure than the gases within the muffle, so that in case of any cracks being formed, no hydrochloric acid escapes into the fire-flues, but vice versa.
A,a, Upright cast-iron cylinders; b,b, brick jacket; c,c, flues; d, e, iron plates arranged like venetian blinds, between which the contact-substance is contained; f, charging hole; g, discharging hole; h, entrance pipe for gas; i, exit pipe for gas.
It is important in all fire-proofing of columns and girders, and in all floor construction, furring and partitions, that there shall be no continuous voids, either vertical or horizontal, which may possibly serve as flues for the spread of heat or flame in case of fire.
The gas-producers constructed by Messrs Siemens Brothers, from 1856 onwards, were provided with a kind of brick chimney; on the top of this there was a horizontal iron tube, continued into an iron down-draught, and only from this the underground flues were started which sent the gas into the single furnaces.
The retort E is charged with ordinary bituminous coal which is submitted to destructive distillation by the heat communicated through the flues n 2 n 2, and is thus converted into coke.
The hot producer-gas formed in V is passed round the retort E in the flues n 2 n2, and ultimately goes away through K to the furnace FIG.
The lateral flues c, c prevent the brickwork from being melted.
